Title: Feeding system and method for communication cable
Inventor: INOUE YOSHIYUKI
IPC: H04B3/44
Filed: 1991-01-17
Abstract: PURPOSE:To attain communication between areas of a wide range and a large number of stations by providing plural branching devices each having at least one changeover circuit with a different current threshold level for changeover depending on a current flowing to a feeding path to a branch point of the feeder. CONSTITUTION:In the case of implementing changeover, A branching device 111 having a small current threshold level to be switched is sequentially switched. A potential of the device 111 is set to a zero voltage equal to ground potential by constant voltage and current control between land stations A121 and B125. Then a current in excess of the current threshold level of the device 111 and less then the current threshold level of a succeeding device 112 flows to a feeder tying stations A121 and E125. As a result, a coil K1 of a changeover circuit 5 in the device 111 attracts one contact of a switch k1, the switch k1 is opened to switch a ground side feeder for the changeover. Since the device 112 with a low current threshold level is switched succeedingly, the communication over a wide range and among a large number of stations is attained.

Title: Refrigerating cycle
Inventor: YAMAZAKI MASAYA
IPC: F25B41/06
Filed: 1988-01-28
Abstract: PURPOSE:To improve the responsibility and eliminate a bypass circuit by providing a temperature-dependant expansion valve which comprises a bleed port in parallel with a valve port through which the cooling medium is supplied to the valve body, said bleed port being opened or closed in response to the cooling medium temperature by means of a valve body comprising shape memory alloy. CONSTITUTION:When the cooling medium temperature is low, like the time when the compressor 11 is started up, the shape memory alloy spring 35 of a temperature-dependent expansion valve 13 is being contracted to allow the valve body 36 to open a bleed port 32. So, a sufficient quantity of the cooling medium can be circulated in a refrigerating cycle 10 in the direction as shown in solid lines. Because of this, a drop in the cooling medium suction pressure can be prevented at the time of heating operation startup while in sleep, for example. As the operation of the refrigerating cycle 10 becomes stabilized by a continued operation of the compressor 11, the temperature of high-pressure liquid cooling medium flowing into the temperature-dependant expansion valve 13 increases. When the liquid cooling medium temperature becomes higher than a set value, the shape memory alloy spring 35 returns and extends to the memorized shape to cause the valve body 36 to close the bleed port 32. Under this condition, the cooling medium can be controlled to a desired overheat level by means of the temperature-dependant expansion valve 13.

Title: Manufacture of motor core for refrigerating machine
Inventor: YAMANAKA KEISUKE
IPC: H02K15/02
Filed: 1981-02-09
Abstract: PURPOSE:To form an iron core having stable securing strength by dipping a temporarily fixed laminated core in coolant resistant solvent type insulating varnish of the prescribed density. CONSTITUTION:After iron core plates punched in the prescribed shape are laminated in the prescribed thickness, they are temporarily fixed by a jig or bolts. Then, they are dipped in coolant resistant solvent type insulating varnish having 25-35% of density, the vaunish is hardened, and temporary fixing is removed. In this case, if the density is less than 25%, varnish immersed between the plates becomes insufficient so that the securing strength is deteriorated. If the density is more than 35%, the varnish is adhered only to the surface of the plates so that the securing strength is deteriorated, and a step of removing excessive varnish is necessary. Accordingly, the core having stable securing strength can be formed by treating it with the coolant resistant solvent type insulating varnish containing 25-35% of density.
